Details
Cylindrical roller bearings are essential components used in various industrial applications to support radial loads and high rotational speeds. It consists of an inner ring, an outer ring, cylindrical rollers, and a cage. The inner and outer rings have raceways, and the cylindrical rollers are arranged between these raceways. The cage keeps the rollers evenly spaced and prevents them from coming into direct contact with each other. NU designs bearings with one integral flange at the inner ring, can accommodate axial displacement of the shaft with respect to the housing as a result of thermal expansion within certain limits.
